VS-307URA250P4 Equivalent & Substitute Parts

Part Overview

The VS-307URA250P4 is a general-purpose reverse rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This component is rated for 2500 V DC reverse voltage with 300 A average rectified current in a stud mount DO-205AB (DO-9) package. The part is classified as obsolete, making identification of suitable substitute components necessary for ongoing system support and procurement planning. Standard recovery characteristics (>500 ns) and reverse polarity technology define its operational profile for high-voltage rectification applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VS-307URA250P4 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Current - Average Rectified (Io): 300 A
• Mounting Type: Stud Mount
• Package / Case: DO-205AB (DO-9)
• Technology: Standard, Reverse Polarity

Voltage Compatibility Criteria: Substitute parts must have a Voltage - DC Reverse (Vr) rating equal to or greater than the original specification. The VS-307URA250P4 operates at 2500 V maximum reverse voltage. Substitutes with lower voltage ratings do not meet the electrical requirements for direct replacement in applications designed for this voltage class.

Compliance Requirements: All substitute parts must maintain RoHS3 compliance and EAR99 export classification to ensure regulatory alignment with the original component.

The R6011030XXYA from Powerex Inc. shares identical mounting, package, and current specifications but operates at a maximum reverse voltage of 1000 V, which is below the original part's 2500 V rating. This part is therefore not suitable as a direct substitute for applications requiring the full 2500 V reverse voltage capability.

Parameter Comparison

Engineering Selection Recommendations

Based on the provided specifications and compliance data, the R6011030XXYA cannot serve as a direct substitute for the VS-307URA250P4 in applications requiring 2500 V reverse voltage operation. The 1000 V maximum reverse voltage rating of the Powerex component represents a 60% reduction in voltage capability, making it unsuitable for circuits designed around the original part's 2500 V specification.

Both components maintain ROHS3 compliance and EAR99 export classification. However, voltage rating mismatch is a fundamental incompatibility that cannot be overlooked in rectifier diode selection.

For applications where the VS-307URA250P4 is specified, direct replacement requires identification of alternative 300 A stud mount DO-205AB diodes with 2500 V or higher reverse voltage ratings from active manufacturers. The obsolete status of the original part necessitates proactive component qualification and supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can the R6011030XXYA replace the VS-307URA250P4 in my application?

A: No. The R6011030XXYA has a maximum reverse voltage rating of 1000 V, while the VS-307URA250P4 is rated for 2500 V. Using a lower-voltage diode in a 2500 V circuit will result in component failure and potential system damage.

Q: What parameters must match for a valid substitute?

A: Current rating (300 A), mounting type (stud mount), package type (DO-205AB/DO-9), and technology (standard reverse polarity) must be identical. Reverse voltage rating must be equal to or greater than 2500 V.

Q: Why is the VS-307URA250P4 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This necessitates identification of alternative components for new designs or system maintenance.

Q: Are there compliance concerns with substitution?

A: Both the original part and the listed substitute maintain ROHS3 compliance and EAR99 classification. However, compliance alone does not ensure electrical compatibility. Voltage rating requirements must be satisfied independently.

Q: What is the operating temperature range difference between these parts?

A: The VS-307URA250P4 operates from -40°C to 180°C, while the R6011030XXYA operates from -65°C to 150°C. The original part has a higher maximum junction temperature capability.

Q: Where can I find a true equivalent for the VS-307URA250P4?

A: Seek 300 A stud mount DO-205AB rectifier diodes with 2500 V or higher reverse voltage ratings from active semiconductor manufacturers. Verify all electrical parameters and package specifications before procurement.
